SPC Carlos Guzman served as the Training Room NCO for B Co. 1-28 IN, 4th BDE, 1ID from approximately April 2013 to Oct 2014. He did a phenomenal job handling 80% of all company administration issues and processing. 1SG (RET) Christopher Hayner, who was the First Sergeant during that time, trusted SPC Guzman to accomplish missions that he would not trust some soldiers who outranked him. SPC Guzman was very proficient at creating and managing tracking systems, was a quick learner, and had a keen ability to train others. 1SG Hayner strongly recommends SPC Guzman as a solid hire.
